InfoComm 08 in Review

Newsworthy AV products and trends at this year’s show.
InfoComm 08 was a packed and energetic show, with important technology on display in all categories — video, audio, AV, and various types of related gear. This year's video trends were examined last issue (svconline.com/
features/infocomm_trends). In this issue, I'll take a look at many of the important audio and AV trends.
Celebrating its 40th anniversary, Community Professional introduced the full-range, three-way column line-array system called Entasys. Each column includes six low-frequency neodymium drivers, 18 2.35in. mid-range drivers, and six 7"×1" Compact Ribbon Emulator (CRE) high-frequency elements. The Entasys line is designed to be modular, according to Community. Multiple columns can be used to create extremely narrow, focused vertical coverage that was previously possible only from powered, steered arrays.
Community also rolled out the first members of its Versatile Low Frequency loudspeakers. With a response down to 70Hz in passive mode or 60Hz using DSP, the VLF208 can function in pairs as a steered bass array. The VLF212 features slot-loaded woofers for extended low-frequency response down to 50Hz in passive mode or 43Hz using DSP. The VLF212 will also be available in a powered version with an integrated amplifier in both portable and installed models.
At the massive Harman Pro Group booth, Crown was displaying its new Macro-Tech i series of power amplifiers: the MA-5000i, MA-9000i, and MA-12000i. Designed for touring, they're expected to find permanent homes in high-powered installations; Crown's installation line, CTs, maxes out at 1500W per channel, but Macro-Tech i offers 2000W, 3000W, and 4000W per channel at 4Ω. Crown also introduced a much smaller amp, the 135MA. Designed for audio installations such as smaller retail stores and medical offices, the 35W mixer/amplifier has a three-input mixer (each input has volume control) for a single audio zone. There's also the 160MA, with four inputs and a 60W amplifier output.
In the same booth, JBL was touting the new 8100 series ceiling loudspeakers for their wide coverage. The 8124 is a 4in. loudspeaker; the 8128 is an 8in. model with extended bass response and a higher SPL output. The 8100 series models feature a sculpted grille and an open back with pre-attached dog-ears. Moving up the in-ceiling loudspeaker ladder, the Control series got new members in the form of Control Contractor 40 models. JBL claims extended bandwidth, improved fidelity, and wider coverage for the loudspeakers — which is made possible by a large-diameter, high-frequency waveguide and low-frequency projection apertures.
JBL also introduced two new line-array elements: the three-way, powered VerTec VT4899ADP and the VT4880ADP ultra-long-excursion, powered subwoofer. The VT4899ADP is capable of producing a maximum of 143dB SPL (1 meter).
